"Planet Earth" type footage would be a natural for the Land. Another alternative would be to move the entrance to over near Canada (same distance from the actual show building as the Land is) and make it "Soarin' Over the Wonders of the World" or something like that with man-made sights, like the Parthenon, Pyramids of Egypt, the Kremlin, Macchu Pichu, etc.
But with regards to "a matter of time", I think it's a matter of quite a lot of time, since the current Soarin' stilll draws so well.
I must think Epcot needs the least help, because it is my favorite park, but it also has the most potential for improvement. Imagine just how wonderful that park could be with the same attention that DCA is getting or the attention TokyoDisneySea got
I agree with all these. Imagination is really a fun little attraction, and the Imageworks as it exists now is OK. If it weren't for the greatness and scale of what was there before, the current attraction would not be nearly as much of a disappointment.
And I don't even mind the Innoventions canopy, really. The LaL tombstones, however, need to go.
